Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524880, here are decompositions:

17 + 31524863 = 31524880
41 + 31524839 = 31524880
71 + 31524809 = 31524880
83 + 31524797 = 31524880
89 + 31524791 = 31524880
113 + 31524767 = 31524880
239 + 31524641 = 31524880
293 + 31524587 = 31524880

Showing the first eight; more decompositions exist.
